Study Material. Stuffed dried skin of a female, about 443 mm. long, from Suri- 

 nam (.?) (Acad. Nat. Sci. Philad., No. 34635).'=' 



Distinctive Characters. This species is sharply marked off from all other Atlantic 

 members of the genus by the large number of teeth and by the great length of the very 

 narrow snout anterior to a line connecting the outer ends of nostrils, this being about i V2 

 times as long as the distance between the inner ends of nostrils, both in the original illustra- 

 tion of the species and in the specimen listed above. In this respect, and in the narrowness 

 of its teeth, it seems to be most nearly related to C. velox Gilbert, 1 898, of the west coast 

 of Central America, but it is separable from velox by its relatively much shorter nostrils 

 and by the fact that the outer margins of the upper teeth toward the corner of the mouth 

 are not notched. 



Description. Proportional dimensions are not available.'^^

 taken from it would be only roughly approximate.
